Detachable swivel apparatus for a beach chair

Abstract

A swivel apparatus is provided for a folding, beach chair. The apparatus includes a load-distributing platform configured like an inverted bowl with a bottom surface for stable engagement with sand and other unconsolidated soils. A swivel mechanism is secured atop the load-distributing platform. A carriage is secured atop the swivel mechanism and has a number of clips for selective fastening to the legs of a folding, beach chair.

I claim:  
     
       1. A swivel apparatus, comprising: 
       a load-distributing platform being an inverted bowl having a bottom surface for engagement with an unconsolidated supporting surface, said bottom surface of said load-distributing platform includes a plurality of elevated and concentric bands for stiffening said load-distributing platform and limiting its sliding on the unconsolidated supporting surface;  
       a swivel mechanism secured atop said load-distributing platform; and,  
       a carriage secured atop said swivel mechanism for selective fastening to the legs of a chair.  
     
     
       2. The swivel apparatus according to claim  1  wherein said carriage includes: 
       a rectangular frame having a pair of opposed side members joined by front and rear end members; and,  
       a pair of clips positioned atop each of said side members with one of said clips being located adjacent said front end member and the other of said clips being located near said rear end member.  
     
     
       3. The swivel apparatus according to claim  2  wherein each of said clips includes: 
       a base for positioning atop one of said side members; and,  
       a pair of opposed, retaining arms extending upwardly from said base, each of said retaining arms having an arcuate shape so as to form an upwardly-opening concavity therebetween into which a chair leg may be releasably snap-fit.  
     
     
       4. A swivel apparatus, comprising: 
       a load-distributing platform being an inverted bowl having a bottom surface for engagement with an unconsolidated supporting surface;  
       a swivel mechanism secured atop said load-distributing platform;  
       a carriage atop said swivel mechanism having a plurality of clips for selective fastening to the legs of a chair, said carriage including:  
       a rigid frame having pair of opposed side members joined by front and rear end members; and,  
       a plurality of clips positioned atop said frame, each of said clips having a pair of opposed, upwardly-extending, retaining arms, each of said retaining arms having an arcuate shape so as to form an upwardly-opening concavity therebetween into which a chair leg may be releasably snap-fit.  
     
     
       5. The swivel apparatus according to claim  4  wherein said bottom surface of said load-distributing platform includes a plurality of elevated and concentric bands for stiffening said load-distributing platform and limiting its sliding on unconsolidated supporting surfaces. 
     
     
       6. A swivel apparatus, comprising: 
       a load-distributing platform being an inverted bowl having a bottom surface for engagement with an unconsolidated supporting surface, said bottom surface having a plurality of elevated and concentric bands for stiffening said load-distributing platform and limiting its sliding on unconsolidated supporting surfaces;  
       a swivel mechanism secured atop said load-distributing platform;  
       a carriage secured atop said swivel mechanism having a plurality of clips for selective fastening to the legs of a chair, said carriage including:  
       a rectangular frame having pair of opposed side members joined by front and rear end members; and,  
       a pair of clips positioned atop each of said side members with one of said clips being located adjacent said front end member and the other of said clips being located near said rear end member, each of said clips including:  
       a base for positioning atop one of said side members; and,  
       a pair of opposed, retaining arms extending upwardly from said base, each of said retaining arms having an arcuate shape so as to form an upwardly-opening concavity therebetween into which a chair leg may be releasably snap-fit.
